For centuries,the only form of written correspondence (通信)was the letters, letters were, and are, sent by some form of postal service, the history of which goes back a long way .Indeed, the Egyptians began sending letters from about 2000 BC,as did the Chinese a thousand years later.
Of course, modern postal service now are much more developed and faster, depending as they do on cars and planes for delivery. Yet they are still too slow for some people to send urgent documents (紧急文件)and letters.
The invention of the fax (传真) machine increased the speed of delivering documents even more. When you send a fax，you are sending a copy of a piece of correspondence to someone by telephone service. It was not until the early 1980s that such a service was developed enough for businesses to be able to fax documents to each other.
The fax service is still very much in use when copies of documents require to be sent ,but, as a way of fast correspondence, it has been largely taken the place of by email ,Email is used to describe messages sent form one computer user to another.
There are advantages and disadvantages with emails. If you send some one an email , then he will receive it extremely quickly .Normal postal services are rather slow as far as speed of delivery is concerned.
However, if you write something by email, which you might later regret ,and send it immediately, there is no chance for second thoughts. At least, if you are posting a letter you have to address and seal(封)the envelope and take it to the post box.There is plenty of time to change your mind .The message is think before you email!

Being a good parent is harder now than it has ever been before. In pressurized modern lives, demands to be a fulfilled individual, a good partner and a good worker, take no account of being a good parent. We haven’t left space for the nurturing parents who are expected to provide what children need. As a result, many families in the western world just don’t work.
Something will have to change. With luck, people in the future will only have children if they really want them. That should mean parenthood is seen as a much more positive promise than it is now, that parents are socially supported, and are admired for doing a good job.
The problem is that in the last generation or so we’ve come to assume that women should want and be able to everything that by tradition men have done at the same time as pretty well everything that by tradition women have done. And it’s just not possible. Since adopting a male life style is demonstrably only another form of submission（顺从）, quite a number of highly educated and economically privileged（优越的）women are now choosing to take career breaks so as to be at home with their children for longer than that poor 18 weeks.
The most welcoming trend in parenting is that men are participating more and more, even that is not free of conflict, however. Intellectually（理智上）, women want men to be equal parents and do their share. But there’s often a contradictory（矛盾的）emotion because children are the last fort of the female power in the family. “I want him to help me but this is my region and being better at it is one of the new things I’ve got as a female.” In truth, although they haven’t had generations of practice, there’s no reason why men can’t raise children as well as women. Men left to cope after bereavement or divorce, as well as some who take on the role of principal career within a partnership, are already doing it.
16.Why is it more difficult today to be good parents?
A. Because parents don’t want to face the pressure of rearing children.
B. Because children are in dependent and don’t need to be taken care of.
C. Because husbands and wives have little time to talk to each other.
D. Because people want to fulfill their own dreams, leaving no time to look after children.
17. We can learn from the passage that _______.
A. people in future will not be as interested in children as people at present
B. parenthood will be considered as a positive commitment as it is now
C. women do better in rearing children than men
D. parents will receive admiration for taking good care of children
18. Nowadays, a lot of highly educated and economically privileged women ________.
A. tend to stay at home for more than 18 weeks
B. tend to adopt a male life style
C. tend to quit their jobs and stay at home
D. tend to be submissive wives
19. It seems that in parenting , women ________.
A. are contradictory in their thoughts. B.demand equality between sexes
C. tend to leave children to their husbands. D. often quarrel with their husbands
20. The underlined word “bereavement” in the para 4 probably means _________.
A. departure of his wife. B. death of his wife
C. return of his wife D. annoyance of his wife

Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slowmoving. There are some aspects(方面) of our unhealthy lives that we cannot avoid. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.
　　For those who do not particularly enjoy competitive sports — and it is especially difficult to do so if you are not good at them — there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.
　　Even after you have found a way for keeping in shape, through sport or gymnastics, you are still only half way to good health, because, according to the experts, you must also master the art of complete mental and physical relaxation(放松). It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activityphysical effort on the one hand and relaxation on the other — which were the natural way of life of our forefathers.

A. causes of unfitness

A. don’t do them very often

14. To be healthy we must _____.
A. keep fit and active B. keep fit and learn to relax
C. be active and practise Yoga D. have a sound mind
15. Our forefathers were healthy because______.
A. their way of life closely connected with both exercise and relaxation
B. they were careful to get plenty of fresh air
C. they spent most of the time out of doors
D. their environment was not polluted

　　The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.
　　This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multibilliondollar Mars research programme. “Turning Mars into a little earth has long been a topic in science fiction,”said Dr Michael Meyer, NASA’s senior scientist for astrobiology (太空生物学). “Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”
Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.
　　But many experts are shocked by the idea. “We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet,” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America’s robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.
In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet’s soil.
　　But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. “Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native lifeforms, all the strange microbes that we hope to find buried in the soil,” said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. “We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said， “This is just wrong.”

A. The project would wipe out all the native lifeforms on the Mars.
B. The project will cost too much money and work.

A. water is a crucial factor for life
B. the project will have little effect on the native lifeforms supposed to live on the Mars
C. Monica Grady is in favour of carrying out the little earth project
D. the idea turning Mars into a little earth is nothing but a science fiction
